Question about Bernina Bernette Deco 600

Not catching stitches / bobbin correctly

I had my machine service not too long ago. They did correct all the tension and cleaned the machine. I was working right along and broke a needle, so I changed the needle and it was working fine. Then bobbin thread runs low (not out). so I take remaining thread of bobbin and fill it back up. Problem is now I can't get the bobbin thread to catch. I've assured the need is not bent, is inserted correctly and threaded right. I thread the bobbin as shown. Just won't catch. I do notice when I take the bobbin plate off and watch the machine work there is no movement at all. I'm assuming that the machanics are suppose to move the bobbin thread toward the needle so that it can catch. though I'm not an expert, I'm just surmising. Anyway, I'm getting really frustrated. I've cleaned out he bobbin area.. I just don't know what else I can do? Does anyone think retiming would work? How do I retime this machine?

Any help sure would be appreciated!

    I have what sounds like the same problem with my Deco 600. It is several years old. Worked great to begin with but the last 5 -6 years has been a big paper weight! I love my ULT problems at all.

    Any help with the deco?

Your timing has been messed up by breaking the needle.  When the needle hit the bobbin race, it shoved the needle bar up and now the needle is not in the correct position to catch the bobbin thread when the race rotates.  The needle has a little dip in the back, called the scarf.  When you take the neddle plate off and watch it move, you should see the little hook pass through the scarf.  That's how it makes the locking stitch and picks up the bobbin thread.  Unfortunately, you will need to take this in to a dealer or service place to have them adjust the needle bar height.  It's not a complicated task so see if they can check it while you wait.  It may be more difficult to fix, like retiming the machine.  But it doesn't sound like you've done any major damage to the mechanism.

When you broke the needle I think you have moved the shaft that brings the needle down ,you can adjust it !

Zig Zag stitch isn't consistent top stitch is sporadic

Remove all the thread from your machine. Make sure to clean around the feed dogs and bobbin area. Loosen the top tension disk all the way to zero & raise the presser foot. Dampen a piece of pearl cotton with rubbing alcohol and pull the pearl cotton gently down between the tension disk a couple of times. Consult your owner's manual and oil as instructed in the manual using ONLY fresh good quality sewing machine, applying 1-2 drops each spot indicated. Install a brand new needle. Avoid old, fuzzy, or bargain bin thread. With the presser foot in the RAISED position, rethread the top thread--verify it is threaded correctly. Reset the upper tension to about halfway between the high & low number. Make sure the bobbin case is threaded properly and verify the bobbin is turning the correct direction in the bobbin case. Install bobbin case in the machine. Test stitch on a scrap piece of fabric.

If it continues to malfunction, you may need to take it for service.

I have a pfaff 1475 and i can not get the tension correct. it is very loose on rt he bobbin side and perfect on the top side. HELP

......... when you did the bobbin drop, did it drop some then stop? Is the bobbin in the correct way (can go in two ways - thread feeds differently into / under the tension 'finger')

Make sure you are threaded correctly. Also be sure that your bobbin is sitting in the casing correctly. If the timing is right and the hook is catching, the thread may not be pulling through correctly. Clean your machine as well. Make sure your tension spring is clean and doesn't need to be tuned up.

My New Home skips stitches. I have cleaned it, changed needles, adjusted the tension and tried different bobbins .

Skipped stitches

1. The needle is not inserted correctly

Remove needle & reinsert needle( flat side towards the back of machine)

2. The needle is damaged

replace with new needle

3. The wrong size needle is being used

Choose a needle to suit the thread & fabric

4. The foot not attached correctly

Check & attach correctly

it's also possible that the machine could be slightly out of time

Missing Stitches

if you have verified the needle is the right one for the machine model and in correctly (long groove the correct direction), that the bobbin is wound and in the case correctly, try a different material and/or thread. If the problem persists, take the machine to a better mechanic/shop. It sounds like it is out of sync. (hook rotation to needle throw).

It sounds as though the problem is with the tension in the bobbin. Check to make sure the thread is pulled through the tensioner on the bobbin case, if it is check and adjust the tension on the case.

Bobbin thread tension issues

There might be a piece of thread or lint caught in the bobbin tension preventing it from functioning correctly.
